DX7 Ram Cartridge

I have been testing the first prototype for the DX7 ram cartridge over the last few weeks. It looks promising, but there are still a few bugs to work out before I can get this boards produced. Much time has passed since the beginning of this project, however, taking time to get it correct is my primary concern.

Here is the latest image of the cart design:

Kits will become available upon creation of a working prototype. Currently development is in its infancy. Please be patient as I still need to find suitable parts to replace the discontinued PROM's, and other required components such as a case.
